Building kokkos-tutorials

The following instructions is for building a new Kokkos library for each exercise. For more details, check Kokkos Tutorials.

  1. Clone the Kokkos Tutorials Repository: The tutorials for the Kokkos C++ programming. You can clone the tutorials with the following command.
git clone https://github.com/kokkos/kokkos-tutorials.git
  1. Load required modules: Kokkos tutorials requires compiler and make to build. Load the following modules. (Note: The modules are as per rhel9 machines. You can’t use it on rhel7 machines.)
module use /opt/scorec/spack/rhel9/v0201_4/lmod/linux-rhel9-x86_64/Core/
module load gcc/12.3.0-iil3lno mpich/4.1.1-xpoyz4t cuda/12.1.1-zxa4msk

  1. Find the GPU architecture of your machine: To find out the GPU architecture of your machine, follow this.

  2. Build with make: Inside kokkos-tutorials folder, go to Exercises folder.In each exercise folder, there is a makefile to build each exercise. Open the Makefile and make the following changes.

KOKKOS_PATH = /path/to/kokkos 
KOKKOS_DEVICES = "<your GPU language>"
KOKKOS_ARCH = "<your GPU Architecture>"

For example,

KOKKOS_PATH = /lore/<username>/Kokkos/kokkos`
KOKKOS_DEVICES = "Cuda"
KOKKOS_ARCH = "Ada89"

After making changes, run the command make -j8

  1. Run the executable: Once configuring and building the exercise, run an exexutable. ```bash ./
